Hey I 'm new here but have had extesive experiance with Palmoplantar pustulosis (PPP). I got it about 16 years ago and my kook doc here in japan put me on a steriod course. Now he's gone and I got a new doc and the same old crap, no info., no this or that. I am in the dumps. But biotin did work. Anybody please if you have anything abt ppp. Thanks, ugly feet and hands but a heart as big as the ocean.
